Yellowish brown, thoracic dorsum with three almost confluent 

 brown stripes ; brown spots on the metanotum. Antenna; pale yellow, 

 darker towards the tip; halteres brownish yellow; abdomen yellow'ish 

 brown (tip broken). Legs dark brown, but femora paler; a small 

 white ring before the tip of the tibiae; three successive white rings 

 at the end of tarsal joints one, two and three. Wings with a pale 

 brownish tinge; stigma brown. 



Habitat. — Brazil (discoverer, Sellow ) ; a single specimen in the 

 Berlin I^Iuseum; sex uncertain, as the tip of the abdomen is broken 

 off. The length, when the abdomen is entire, must be about 14 mm. 

 The number of joints of the antenna; is certainly more than eleven 

 (this number I counted in T. opilio). 



The above is taken verbatim from Osten Sacken's original descrip- 

 tion; the type specimen seems to be the only one so far taken.
